 Posted: Sun Jan 26, 2025 3:33 am Post subject: [SOLVED] No audio playback (except for HDMI) from pipewire |
 |
|
I'm trying to use pipewire as the sound server for pulse audio. While I can get audio from HDMI, it doesn't work for the onboard intel card. I'm not sure if it's pipewire to blame but I was able to get the audio from the same pulseaudio profile before I switched to pipewire.
| Code: |
$ emerge -pv --nodeps pipewire libpulse pulseaudio pulseaudio-daemon alsa-plugins rtkit

media-sound/pulseaudio-daemon is not installed.
The sound cards:
| Code: |

Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 1: Generic Digital [Generic Digital]
Subdevices: 1/1

And according to Pulseaudio:
| Code: |
$ pactl list cards | egrep Card\|alsa.card_name\|Name
Card #50
Name: alsa_card.pci-0000_01_00.1
alsa.card_name = "HDA NVidia"
Card #51
Name: alsa_card.pci-0000_00_03.0
alsa.card_name = "HDA Intel HDMI"
Card #52
Name: alsa_card.pci-0000_00_1b.0
alsa.card_name = "HDA Intel PCH"
|
Trying HDMI:
| Code: |
$ pactl set-card-profile alsa_card.pci-0000_00_03.0 output:hdmi-stereo
$ pactl set-card-profile alsa_card.pci-0000_00_1b.0 off
$ gentoo-pipewire-launcher restart
|
`mpv --ao=pulse file.wav` produces the sound. (mv -ao=alsa would also work, thanks to `alsa-plugins[pulseaudio]`) . The output of `wpctl status` would be like:
| Code: |

Switching to the Intel card:
| Code: |
$ pactl set-card-profile alsa_card.pci-0000_00_03.0 off
$ pactl set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo
|
`mpv --au=pulse` errors:
| Code: |
[ao] Failed to initialize audio driver 'pulse'
Could not open/initialize audio device -> no sound.
Audio: no audio
Exiting... (Errors when loading file)

But.. VLC would still be able to play! At this point `wpctl status` is like

If I re-launch pipewire (`gentoo-pipewire-launcher restart`) it changes pulseaudio profile:
| Code: |
$ pactl list sinks short
54 alsa_output.pci-0000_00_1b.0.iec958-stereo PipeWire s32le 2ch 48000Hz SUSPENDED
|
It changes the default sink to "digital stereo" and if I don't change profile again, `mpv --ao=pulse` (or alsa) doesn't error but doesn't produce any sound either. `speakertest -D sysdefault` will producde sound from the speaker but `speakertest -D default` and `speakertest -D pulse` don't.
I used to see some error/warning logs related to realtime scheduling but output I posted are produced after I resolved the logs (by recombiling kernel and installing rtkit)
Update
Damn it, the speaker was connected to rear speakers port and somehow this used to work in Pulseaudio. I wasn't smart enough to figure this out until I found this guy's post, so I keep this post here too. |
